Primacoustic presents solution for awkward commercial ceilings

Primacoustic has released two sound absorption products – ThunderTiles, a T-bar shaped ceiling tile, and VoxGuard, a near-field ambient noise absorber. ThunderTiles have been designed to be retro fitted into dropped ceiling systems – common in offices and other commercial buildings – and enable sound absorption into areas that can't traditionally accommodate free-hanging panels due to weight restrictions. By combining sound absorption with a heavy gypsum backing board and T-bar frame, the board is ‘free to resonate like a spring, which both absorbs low frequencies while stopping sound’.

The ThunderTiles are described as ‘combining the sound absorption advantages of high-density glass wool fibre with the sound blocking capability of gypsum board’. The panels are made from a ¾-inch layer of 96kg/m³ high-density fibreglass that is coated with a fine micromesh facing.

Primacoustic product specialist Jay Porter explained, ‘Most folks think that one can stop sound by simply putting up a bunch of acoustic panels on a wall. This can help as it can reduce the reverb and echo inside the room, but if you want to stop sound from escaping, you have to both decouple transmission lines and add mass to the equation’.

The company has also introduced VoxGuard, a high-performance ambient noise absorber designed to surround microphones and reduce unwanted sounds. The absorber works by creating an acoustic boundary around the mic, which contains the voice whilst reducing room reflections.

Made from an ABS outer surround shell, the unit’s light weight aims to eliminate stability problems stemming from awkwardly placed microphones, reportedly allowing for its use with round base stands, tripods and large studio booms.

The VoxGuard includes pressure release slots in its ABS shell to allow acoustic pressure to escape, eliminating low frequency resonance. Primacoustic states that the product is ideal for ‘recording studio vocals, voice-over tracks for film and TV postproduction, podcasting and field recording.
